JOSEPH J. HOTCKISS, OF RALEIGH, NORT CAROLINA.

" v DrsrENsINe ArPAnATUs.

To all whom t may concern.'

Be it known that I, JOSEPH J. HOTCH- Kiss, a citizen of the United States, residing at Raleigh. in the county of Wake and yState of North Carolina, have inventedy a new and useful Dispensing Apparatus, of whichthe followingA is aj specification. Y

This invention relates to apparatus'for dispensing vinegar and other `liquids in measured quantities, one of its objects being to provide simple and eiiicient `means whereby the operationof the forcingfmechanism will be automatically stopped when the predetermined -amountof liquidihas been discharged. I

Apparatusof this type as heretofore constructed have usually been objectionable be# cause it has been possible to eject'therefrom more than the desired quantity, this being y due to the fact that no means has been emploved for automatically stoppingv the op; eration as soon as the desired amount has been dispensed.. Obviously this liasresulted in considerable loss of liquid not.V paid for by the purchaser. n y y Une ofthe obiects ofthe presentinvention is to provide simple, etlicient and compact mechanism whereby'a desired quantity of liquid can be accurately measured. there being novel means for indicating not only the selected quantity of liquid to be dispensed but valso the price to be charged for said quantity at any given charge per unitloff measure. y f y,

yWith the foregoing `and other objects in view which willl appear asl the description proceeds, the invention resides inthe `combination and arrangement of parts and'in the details of construction hereinafter described and claimed, 'it being understood that changes in the precise embodiment of the invention herein disclosedcanbe made within ythe scope of what is clamechwithcut departing from the spirit of the invention.

` In `the accompanying drawings'the preferred form 'of the invention has been'yshown. Insaid drawingst'- Figure 1y is a frontl elevation fthe'apparatus. l

Referring to the figures by characters of reference l designates a housing of 'any suitable configuration which may be .placed upon a counter or the like. Extending within the front face of this housing is a slot 2 above. which is arranged a chart 3 preferably divided into two sections which are coeXtensive, there being located atthe left end of gallon Vor other unit of measure. i-arrangedalong the top of each section of the chart are numerals indicating a unit of measure and fractions thereof. For example, if one gallon'of liquid is capable of being dispensedk at one operation of theapparatus, then'the characters along the top of each section of the chart would designate one gallon and fractions thereof. The right handsection of thechart is used for carrying forward the values indicated on the left hand portionof'the chart. Where the left hand portion indicates values up to 20 cents, then the characters in the end column 'of Ithe right hand portion will indicate values ranging from 20 cents upwardly .per unit of measure.

Arrangedl in the lower portion of thc housing l is aipump 4 of any desired construction. the same being preferably of that type utilizing a reciprocating piston having a Vrod 5 extending therefrom. ToV this rod y Patented Apr. 9,Y 1918. Appiication iiieaiiecember 2, 191s. serial No. 134,654.

This position of the palets has een illustrated in Fie; 7.

Assuming' that it is desired to dispense an amount of liquid equal to that indicated by the highest eliafaeter on thechai'which is the maximum capacity of the appaiatusa-t one opeiation, the 'ope'iato'i' 'giasps thetwo i pieces 28 and 29 and presses the finger Y oWaicl the linge? piece 528 to disenf .in the. feed sciew' Whe t... en shifted longitiichne Tj; to

bring the pointers to the graduations indicating the unit of measure selected. During this operation thelever 48 and its-holding mechanism remains in the position illustrated in Fig. 7.' Upon completion of the adjustment described the operator rotates shaft lO so that motion is transmitted to the feed screw and to the pump piston. Liquid is promptly ejected from the nozzle 16 by the reciprocating piston and the carriage 25 moves gradually along its guide rod 27 and the feed screw 20. As soon as the pointers 41 reach the zero graduations on the chart, the tripping plate 38 pushes the depending linger 43 so as to swing lever land cause the spring tongue 44 to pass over pin 50. Thus the pin will be held depressed until the limit of movement ofthe carriage is reached whereupon the switch will pass from above the pin 50 and the weighted arm of lever48 will cause the depending portion 49 to swing into position above the piston rod 5. Said rod will therefore be held against further movement and no more liquid can be dispensed until the carriage isfpulled away from the fingerl43.

combination with liquid forcing means, of a ger pieces upontlie carriage, a screw engag ing element upon the carriage, means operated by the movable finger piece for disengaging said element from the feed screw, an indicator movable with vthe carriage, and means controlled by the carriage when brought to a predetermined position, for locking the liquid forcing means against movement.

3. In liquid dispensing apparatus, the combination with liquid forcing means including a reciprocating element, of a lever having a downwardly extending portion, a movable switch including a resilient tongue and a deiecting flange above the tongue, means upon the lever and normally engaging the flange to hold the depending portion of the lever out of the path of the reciproeatingV element, and means for shifting the switch to release the lever. lower inclined edge of the Harige 45 detlect- 'Y 4. In liquid dispensing apparatus, the combination with liquid forcing means including a reciprocating element, of a lever having a downwardly extending portion, a movable switch-including a resilient tongue and a deflecting flange above the tongue, means upon the lever and normally engaging the flange to hold the depending portion of the lever out of the path of the reciprocating element, a carriage, an indicator carried thereby, means for simultaneously shifting the carriage and actuating the liq- Vuid forcing means, and .adjustable means upon the carriage for shifting the switch to release the lever.
